Use
Pyridine (Formula is C6H5N) is a six-membered heterocyclic compound containing one nitrogen heteroatom. It is structurally related to benzene, with one methine group (=CH-) replaced by a nitrogen atom. Just like benzene, Pyridine has same electronic structure, and it is still aromatic, so it is also known as nitrogen benzene and azobenzene. Pyridine is a colorless liquid with special odor at room temperature, and melting point is -41.6 ℃, and boiling point is 115.2 ℃. It will form azeotropic mixture with water, and boiling point of the mixture is 92 ~ 93 ℃(The property is used to purify pyridine in industry.) Its density is 0.9819g / cm3. Pyridine is soluble in water, ethanol, ether and other organic solvents, and itself can also be used as solvent. Pyridine was discovered in 1849 by the Scottish chemist Thomas Anderson as one of the constituents of bone oil. Two years later, Anderson isolated pure pyridine through fractional distillation of the oil.
